Application led March 29, 1928. Serial No. 265,604.

This invention relates to spools and especially to those of the larger and heavier types used in the textile industry. It aims to provide spools of improved construction and character adaptedto endure the abusive and destructive treatment to which they are generally subjected in the mills.

The invention will be best understood from the following description with reference to the accompanying drawings, wherein a practical embodiment thereof is illustrated 1n the form of a jack-spool employed 1n certain mill operations under particularly destructive conditions.

In said drawings:

Fig. 1 is an elevational representation of a spool of the invention with parts at one end shown detached in relation of assembly;

Fig. 2 is an elevation of the assembled spool with the parts at one end shown sectionally;

Fig. 3 illustrates a section through the spool barrel on the line 3-3 of the preceding figure upon enlarged scale; and

Fig. 4 is a plan view of one of the parts hereinafter described.

Referring to the drawings, the barrel 5 of the illustrative spool is formed by a Section of spirally-corrugated metallic tubing of minimized wall-thickness combining the advantages of lightness and strength.

An important advantage in forming the barrel of metal is that it will not be mutilated by cutting off yarn thereon as in the case of spools with wooden barrels for example, which are easily slivered, quickly mutilated and soon rendered useless.

Metal tubing with spiral corrugations is found peculiarly appropriate for spool barrels, especially for the heavier elongate spools which ordinarily vary from 30 to 80 inches in length and are rotated by drums bearing on their loading barrels. -Spools having barrels of said character will always work smoothly on the driving drums, but

spools having warped, mutilated or longi l tudinally slivered barrels will Work irregularly and give rise to heavy poundings of the drums so that their use mustbe aba-n- 5 doned.

The diameter and Wall-thickness of the tubular sections used for the barrel will of course depend upon the size and character of spools desired, but thin-Wall material will ordinarily possess'the necessary strength regardless of the diameter and length of the sections.

Means serving to secure heads to the barrel ends while providing gudgeons for rotatably supporting the spool are represented by bolts 6 supported in opposite ends of the barrel so as to project axially therebeyond. Said bolts having reduced end and threaded shank portions, are in this instance provided with polygonal heads for fastening inside the barrel. The gudgeon-bolts are supported in the ends of the barrel by plate-members 7 nonrotatably fitting Withinthe barrel on diametrical planes or at right angles to its axis. In the simplified construction shown, said platemembers are peripherally scalloped in conformity with the corrugated barrel interior and are accordingly rendered non-rotatable except with simultaneous movement longitudinally of the barrel.

In this instance the aforesaid bolts are outwardly extended through said plate-members with their heads engaging ythe inner sides thereof and are locked against rotation by lug-portions 7 punched out of the body of the plate-members against the bolt heads. In effect, the bolts are thus secured to the plate-members as substantially unitary parts thereof. Obviously, they may be screwed or Welded to the plate-members, or the Vlatter may be formed as heads of the former, although the illustrated connection is considered more expedient and economic.

Movement of the bolt-carrying plate-members toward the open lends of the barrel is limited by indent-ations 5a of the barrel body made at spaced points on diametrical planes near its ends. .By this simple expedient, the plate-members are not only limited in outward movement, but withdrawal of the bolts is made impossible, unless the aforesaid indentations of the barrel body are forced outwardly to disengage the plate-members. The barrel is accordingly provided with selfcontained gudgeons serving to hold heads to the opposite ends thereof.

Over the gudgeon-bolts in the ends of the barrel, block-rings or washers 8 are slipped against the outer sides of the plate-members kn for spacing purposes as will appear.

In the extremities of the barrel, plates 9 are non-rotatably fitted with their outer faces held by said block-rings substantially flush with the barrel edges when the aforesaid plate-members are drawn to their limits of outward movement. In the form shown, said plates are peripherally scalloped in conformity with the barrel interior so as to be nonrotatable therein similarly to the plate-members, and at opposing poi-nts are punched to provide outwardly projecting lug-portions 9a adapted to engage in applied spool heads for locking the latter against rotation independently of the barrel.

'Io the ends of the barrel, centrally apertured heads 10 of,disclike form are applied over the gudgeon-bolts with their inner faces abutting the barrel edges. In this instance, diametrically opposed recesses 10a are provided in the heads to receive the extended lug-portions 9a of the aforesaid extremital plates by which the'heads are locked against rotation independently of the barrel when clamped thereagainst.

Said heads, which in jack-spool constructions vary from 6 to 14 inch diameters, are in this instance formed of hard vulcanized fibre, which is found to be a most suitable material because of its light and non-breakable qualities. Of course, the heads may be l formed of metal, wood or other material if preferred.

Over the extended gudgeon-bolts, lock- Washers 11 are placed against the outer faces of the applied heads for an obvious purpose.

Onto the threaded portions of the extended gudgeon-bolts, outer plates or nuts 12 are screwed against the outer faces of the heads so as to draw the bolts with plate-members to their outward limits of movement and press or clamp the heads firmly to the'ends of the barrel, where they are held by the aforesaid underlying lock-washers. The undersides of said outer plates or nuts are advantageously notched or knurled radially as represented in Fig. 4, to provide a ratchet-like engagement with the lock-washers and insure against their becoming loosened on the bolts and relieving the pressure on the heads.

Spools of improved construction and substantially indestructible character are thus provided. Apart from 4the more important advantages of strength, durabilityl and lightness, they embody the advantage of permitting removal of the head at either end without disturbing the other, as the gudgeons are independently fixed in the barrel. Moreover,

lation of extension therefromwhen the heads are applied thereto in the manner described. The simplicity and superiority of the claimed spool construction over spools heretofore own and used will be readily appreciated by those familiar with the art.

As the invention comprehends various modifications of spool construction, the appended claims are not intended to limit the same to the illustrated construction alone or to the specific form and arrangement of the parts described.
